Reffing Experience/Preferences (Quaffle, Snitch, both): Quaffle, one "match" of snitch. I reffed two official matches, one or two NAPs and practiced with HQT.
Summer Availability: Gone from 21st to 31st July, though if it is told a few days beforehand, I might find a cafe or something, where they have internet access for a couple of hours. Otherwise free. As for hours, anything between 11 AM HOL and 10 PM HOL, optimal 5 PM to 9 PM HOL.

Reffing Experience/Preferences (Quaffle, Snitch, both): Both! But I still prefer Snitch.Summer Availability: I don't have any major plans this summer, but my schedule is a pain to explain. Just ask me and I'll tell you whether I'm free to ref or not.

Reffing Experience/Preferences (Quaffle, Snitch, both): I can ref both; I've reffed for both SQL and regular season quidditch.
Summer Availability: My work schedule is done weekly so nothing is completely set in stone, but I should be able to get most Saturdays off. I work doubles on Sundays, so it's a no-go there. If you're in need of a ref, just poke me and I'll try to clear up my schedule.
